WRENCH.

Application filed August 11, 1926.

This invention relates to wrenches the general object and characteristicof the invention is a provision of ratchet means which may be manuallyalternated whereby the wrench may be used to tighten or loosen from asingle position.

WVith the above and other objects in view the invention further includesthe following novel features and details of construction to behereinafter more fully described and pointed out in the appended claim.

In the drawing: 1

Figure 1 is a longitudinal section of the invention Figure 2 is anelevation thereof with parts broken away and illustrating the ratchetmechanism therefor.

Figure 3 is an elevation of the invention per se.

Figure 1 is an end elevation of the wrench.

Figure 5 is a vertical sectional View on line 55 of Figure 1.

Figure 6 is an end elevation taken from the opposed end of the wrenchwith relation to Figure 41.

Referring to the drawing in detail wherein like characters of referencedenote corresponding parts. The reference character 10 indicates acylindrical body portion having a bolt member or shaft 11 extendingcentrally therethrough and having its opposite ends fitted withinenlarged portions 12 of ratchet members 13 and being encircled bycompression springs positioned therein, substantially as illustrated inFigure 1 of the drawing. The intermediate portion of the bolt member orshaft 11 providing a square portion 11 whereby simultaneous rotation ofthe body portion and bolt member is assured. The meeting ends of thetubular body portion and ratchet members 13 having intermeshingoppositely disposed ratchet teeth 15 provided thereon and held in suchrelation through the instruinentality of the springs 14 encircling theend portions of the bolt 11. Received upon the body portion 10 andappropriate portions of the ratchet members 13 is a sleeve member 16having an elongated slotted portion 17 provided centrally thereof andwithin which is received a projection 18 provided upon the outer side ofthe tubular member 10. The ends of the sleeve 16 further provide cut outportions 19 therein for alternately receiving corresponding projections20 provided upon the outer sides of the respective ratchet Serial No.128,606.

member 13. Said sleeve 16 further provides apertured portions 21 uponthe diametrically opposite side tl'iereof with respect to the elongatedslotted portion 17 within which a spring pressed ball 22 is selectivelyreceived when receiving the projections of either of the ratcheti'ncinbers 13 and for holding the same rigidly in engagement therewithagainst accidental and retrograde movement.

The outer and opposite end portions of the respective ratchet members 13are provided with rectangular and hexagon shaped portions 23 and 24respectively; adapted for engagement with the convention form of chuckor socket 25 and an operating handle 26 substantially as illustrated inFigure 1 of the drawing.

In the use and operation of the above entitled application, it isclearly apparent andmanifest that upon sliding movement imparted to thesleeve member 16 the respective projections 20 may be alternatelyreceived within the cut out portions 19 of the sleeve to reverse themovement of the chuck or socket 25 in order that nuts or headed boltsmay be rotated in opposite directions from the first or originalposition.

From the foregoing description and accompanying drawing it will be notedfrom the full line positions of the sleeve member 16 in Figures 1 to 3inclusive that the projection 20 carried upon one of the ratchet members13 provided with the portion 23 is received within an adjacent cut-outportion 19 in the periphery of the sleeve to rigidly hold theaforementioned ratchet member, sleeve and hotly portion 10 as a unitarystructure. The ratchet member 13 having the portion 24 upon one end forconnection with the handle member 26 is left free of locking engagementwith the body portion 10 and from the illustration in Fig ure 2 of thedrawing the ratchet portions thereof may rotate the body portion andfirst mentioned ratchet member 13 in a clockwise direction.

From the aforementioned position, when it is desired to loosen a nut orheaded bolt, the sleeve member 16 may be shifted to the dotted lineposition as illustrated in Figure 2 of the drawing in order that thefirst mentioned ratchet member may be released. The ratchet member 13having the portion upon one end for connection with the handle member 26will then be held. rigidly with the body portion and sleeve. Thedisposition of the ratchet connections between the respective sleeves 13with the body portion 10 Will permit the wrench to be 0perated in a,counter-cloclnvise movement. The Wrench, however disposed, may bealternated, as to the direction of travel, by the shifting of the sleevemember 16.

The spring: 141; permit necessary ratchet connection between therespective ratchet members 33 and the adjacent ends of the bot v portion10.

The invention is; susceptible ol varioue changes in its torm,proportioiis and minor detailsof construction and the right is hereinres-erred to make such changes as properly fall within the scope ot theappended claim.

Having thus described my invention what is claimed is:-

A ratchet wrench com prising a body portion provided With a projectionupon its outer side, a bolt member disposed axially oi? thelonp'itndinal center thereof, ratchet members dispoeed, in end to endrelation upon the opposed ends of the body portion and receiving theextremities of the bolt member Within enlarged bores therein, e ningecarried Within the bores encircling the adjacent portions of the bolt;to retain the ratchet portions ot. the ratchet members in constant meshwith the abutting ends of the body portion, projections carried by theratchet members a sleeve men'lber slidabl v mounted upon the bodyportion provided with an elongated slot receiving the projection carriedby the body portion, said sleeve in further provided with. cut-outportioim Within the opposed peripheral edges thereof adapted foralternately receiving the projections carried by the ratchet inelnl'iersand guided duri 1 the aeeociaion thercoi; by the pzee'cncc of theprojectimi and slot con-- ncction between r-aid sleeve and body p01-tiozn and a spring; pressed ball carried by the body portion adapted forreception Within opening a in said sleeve to preserve interfitting;-engagement of the cut-out portions; and projections.

in testimony whereof l. atlix my signature.
